FAQS
What should I do if I haven't filed my US taxes before?
If you have consistently failed to file your US tax returns, being discovered by the IRS could result in substantial penalties.
However, there is no need to worry. The IRS offers compliance procedures designed to encourage taxpayers with non-willful tax delinquencies to voluntarily come into compliance,
Moreover, there is a possibility of being completely exempt from penalties.
Please follow the two steps below to confirm if you qualify for the IRS compliance procedures to avoid penalties,
Step 1:
Confirm Your Status Matches Either (a) or (b)
a. U.S. Citizens or Green Card Holders,You must have resided outside the United States for at least 330 full days in at least one of the last three calendar years.
b. Non-U.S. Resident Aliens,You must have failed to meet the Substantial Presence Test (i.e., were present in the U.S. for fewer than 183 days) in at least one of the last three calendar years.
Step 2:
"Your failure to file was non-willful, meaning you were unaware of your U.S. tax obligations, and the IRS has not yet contacted you regarding an examination or audit.
If you satisfy both steps above, you may be eligible to utilize the IRS Streamlined Filing Compliance Procedures. By voluntarily disclosing your tax returns for the most recent 3 years and FBARs for the most recent 6 years, you may have the opportunity to avoid all penalties.

FAQS
Who says the FBAR only targets big players
and ignores small ones?
On May 4, 2022, Dr. Mingqing Xiao, a mathematics professor at Southern Illinois University, was convicted by a federal jury. He was found guilty on three counts of filing false or fraudulent tax returns with the Internal Revenue Service (IRS) and one count of willfully failing to file a Report of Foreign Bank and Financial Accounts (FBAR).
Evidence presented at trial showed that Dr. Xiao opened a foreign bank account with Ping An Bank in China in 2016. Between 2016 and 2020, he made monthly deposits into this account from Shenzhen University in China, with other funds also originating from China. By 2020, the balance in Dr. Xiao's Chinese account had exceeded $100,000. However, he failed to accurately report his financial accounts in China to federal authorities for the years 2017, 2018, and 2019.

The Internal Revenue Service (IRS) emphasizes the integrity and accuracy of taxpayer filings. Failure to disclose foreign financial accounts to the IRS or filing false tax returns constitutes tax fraud.Preparing false tax returns carries a maximum penalty of three years in prison, one year of supervised release, and a $100,000 fine. Charges for willfully failing to file an FBAR can result in a maximum sentence of five years in prison, three years of supervised release, and a $250,000 fine.

Organizational structure of companies in the United States
Organizational structure of companies in the United States
To register a company in the United States, it is necessary to be clear about the type of company to be established. Due to the relationship between different types of companies, your responsibilities, tax obligations, and the future direction of the company. The following is an introduction to the basic composition and responsibility attribution of different types of US companies:
1.Sole Proprietorship
Sole proprietorship refers to an individual who owns a non stock company and its establishment is the simplest.
2. Partnerships
Partnership companies are usually composed of two or more people, and their establishment is relatively simple and cost-effective.
3. Limited Liability Company,LLC
Due to the fact that most states do not have restrictions on the ownership of limited liability companies, their members can be individuals, corporations, other LLCs, or out of town entities, and their establishment is relatively relaxed. In most cases, a limited liability company protects you from personal liability. If your limited liability company faces bankruptcy or litigation, your personal assets will not be at risk, making the establishment of a limited liability company more popular.
4. Corporation
It is an independent and clear legal entity with higher establishment costs compared to other types of companies. The company owner is independent of shareholders, and if shareholders leave the company or sell their shares, the joint-stock company can continue to operate relatively undisturbed.
